it represents instantaneous rate of reaction ans(c)
The termrateis often used to describe the change in a quantity that occurs per unit of time. The rate of inflation, for example, is the change in the average cost of a collection of standard items per year. The rate at which an object travels through space is the distance traveled per unit of time, such as miles per hour or kilometers per second. In chemical kinetics, the distance traveled is the change in the concentration of one of the components of the reaction. The rate of a reaction is therefore thechangein the concentration of one of the reactants with respect to time
We might try, for example, to measure the infinitesimally small change in concentration [--] d(X) [--] that occurs over an infinitesimally short period of time [--] dt. The ratio of these quantities is known as theinstantaneous rate of reaction.
